K&N 33-2438 Air Filter Product Reviews

Wednesday, July 18, 2018 - Part 33-2438
I have used K&N Air Filters for years and have cleaned are reused them. I have never had a car long enough to check out the long range warranty, but I suspect the would last that long. The simple fact that the filter can be cleaned and reused is good enough. Even though initially more expensive, the price is recovered by using it over and over.....

Replaced air filter on my 2018 4Runner TRD Off Road with drop in K&N filter. Definite improvement in acceleration, with aggressive sound. Used K&N air filter on 2004 4Runner Sport, easy to clean and recondition. Pays for itself year after year, worth the investment.
